C'm on John.  Name him.  No-one else seems to want to even try.  You obviously know him.

That's him Jack.  Who do you have ?

David Livingstone (/lvstn/; 19 March 1813  1 May 1873) was a British physician, Congregationalist, and pioneer Christian missionary^[2] with the London Missionary Society, an explorer in Africa, and one of the most popular British heroes of the late 19th-century Victorian era. He had a mythical status that operated on a number of interconnected levels: Protestant missionary martyr, working-class "rags-to-riches" inspirational story, scientific investigator and explorer, imperial reformer, anti-slavery crusader, and advocate of commercial and colonial expansion.

His fame as an explorer and his obsession with learning the sources of the Nile River was founded on the belief that if he could solve that age-old mystery, his fame would give him the influence to end the East African Arab-Swahili slave trade. "The Nile sources," he told a friend, "are valuable only as a means of opening my mouth with power among men. It is this power which I hope to remedy an immense evil."^[3]:289 His subsequent exploration of the central African watershed was the culmination of the classic period of European geographical discovery and colonial penetration of Africa. At the same time, his missionary travels, "disappearance", and eventual death in Africaand subsequent glorification as a posthumous national hero in 1874led to the founding of several major central African Christian missionary initiatives carried forward in the era of the European "Scramble for Africa".^[4]

His meeting with Henry Morton Stanley on 10 November 1871 gave rise to the popular quotation "Dr Livingstone, I presume

I just guessed this would be the mate of Livingstone, and I think I'm right !!! Henry Morton Stanley

Thank you Jack. Here's an easy one for you:

You have it Sheba. Over to you:

Is it Rudolf Valentino

No other brave people out there willing to even guess ?

I hoped you would chime in with that clue John.  Didn't want to use it myself, in case anyone got the wrong idea.

G'day Sheba. I have worked out who he is but did not like the coward statement. I will add that Noel knows the answer.

Cheers.

You got him Sandy.  Who do you have for us. ?

I'm sure nothing derogatory was really meant in that clue Jack. 

Sir Noël Peirce Coward (16 December 1899  26 March 1973) was an English playwright, composer, director, actor and singer, known for his wit, flamboyance, and what Time magazine called "a sense of personal style, a combination of cheek and chic, pose and poise".^[1]

Coward attended a dance academy in London as a child, making his professional stage début at the age of eleven. As a teenager he was introduced into the high society in which most of his plays would be set. Coward achieved enduring success as a playwright, publishing more than 50 plays from his teens onwards. Many of his works, such as Hay Fever, Private Lives, Design for Living, Present Laughter and Blithe Spirit, have remained in the regular theatre repertoire. He composed hundreds of songs, in addition to well over a dozen musical theatre works (including the operetta Bitter Sweet and comic revues), screenplays, poetry, several volumes of short stories, the novel Pomp and Circumstance, and a three-volume autobiography. Coward's stage and film acting and directing career spanned six decades, during which he starred in many of his own works.

At the outbreak of the Second World War Coward volunteered for war work, running the British propaganda office in Paris. He also worked with the Secret Service, seeking to use his influence to persuade the American public and government to help Britain. Coward won an Academy Honorary Award in 1943 for his naval film drama, In Which We Serve, and was knighted in 1969. In the 1950s he achieved fresh success as a cabaret performer, performing his own songs, such as "Mad Dogs and Englishmen", "London Pride" and "I Went to a Marvellous Party".

Coward's plays and songs achieved new popularity in the 1960s and 1970s, and his work and style continue to influence popular culture. He did not publicly acknowledge his homosexuality, but it was discussed candidly after his death by biographers including Graham Payn, his long-time partner, and in Coward's diaries and letters, published posthumously. The former Albery Theatre (originally the New Theatre) in London was renamed the Noël Coward Theatre in his honour in 2006

I thought at first glance John McEnroe, but I don't really think that's right.  Think we need a clue Sandy.

Tricky all right.  Hope some-one else can get him.

Well there is a list of clues and you could joke that he was born in a Casino

Well not born in a Casino but born in Casino. Have you Googled John's clues?
